Hair colouring kit

ABSTRACT

A kit for colouring hair comprising: i) a first container containing a composition comprising an oxidative dye; and ii) a second container containing a composition comprising a per-oxygen generating material, in which the second container comprises sides of height X mm, a first end closed by a bottom of external diameter Y mm and a second end opposite the first, having a opening of internal diameter Z mm in which the ratio of X to Y is less than 1:1 and the internal diameter Z mm differs by 15% or less from the external diameter Y mm and in which the internal diameter Z mm is from 60 to 80 mm.

The present invention relates to a kit for dyeing of keratin fibres, in particular human keratin fibres such as the hair.

BACKGROUND OF THE INVENTION

Commercial dyes for consumer use historically have been sold as a kit in which the per-oxygen containing developer is packaged in a bottle and the oxidation base is sold in a pliable tube.

WO 11/099485/EP 2 535 036A (Kao) discloses a kit for dyeing or bleaching hair comprising a first part, a second part, a thickening composition, and an openable and closable airtight container for mixing.

WO 06/066670/US 2007/0205129 (Henkel) discloses a dish for mixing hair treatment agents, particularly hair colouring products.

U.S. Pat. No. 5,972,043 (Galvan) discloses a device for the mixing and application of hair colouring products which is a two-piece mixing bowl with an aperture for a mixing and application brush.

The present invention is concerned with a kit for colouring hair in which the per-oxygen containing composition is contained in a pot. Study of consumers has shown that they prefer to apply the colouring product using two hands and as such need a steady container that does not need to be held during application of the product. The containers described above do not enable the consumer to apply the colouring product to the hair in this manner.

SUMMARY OF THE INVENTION

The present invention related to a kit for colouring hair comprising:

-   i) a first container containing a composition comprising an     oxidative dye; and -   ii) a second container containing a composition comprising a     per-oxygen generating material, in which the second container     comprises sides of height X mm, a first end closed by a bottom of     external diameter Y mm and a second end opposite the first, having a     opening of internal diameter Z mm in which the ratio of X to Y is     less than 1:1 and the internal diameter Z mm differs by 15% or less     from the external diameter Y mm and in which internal diameter Z mm     is from 60 to 80 mm.

The invention also relates to a method of colouring the hair using the kit described above comprising the following steps:

-   i) adding the contents of the first container to the second     container; -   ii) mixing the contents; -   iii) applying the product to hair; -   iv) rinsing the hair with water.

DESCRIPTION OF THE INVENTION Second Container

The second container containing comprises sides of height X mm, a first end closed by a bottom of external diameter Y mm and a second end opposite to the first, having a opening of internal diameter Z mm in which the ratio of height X mm to external diameter Y mm is less than 1:1; preferably the in which ratio of the height X mm to external diameter Y mm of the second container is from 4:5 to 1:2. The internal diameter Z mm is from 60 to 80 mm, more preferably from 65 to 75 mm and differs by 15% or less from the length of the external diameter Y mm.

Preferably the height X mm of the second container is from 45 to 65 mm; more preferably from 50 to 60 mm.

Preferably the second container is has a volume from 100 to 300 ml, more preferably from 180 to 260 ml.

Preferably the second container comprises a rigid casing in which the casing comprises polypropylene (PP), polyethylene (PE), or combinations thereof.

Preferably the sides of the second container narrow below the opening to form a neck within the container. As a consequence of the neck formation a lip is formed within the second container which facilitates removal of excess composition from the fingers.

Preferably at least one part of the second container is deformable, this allows for gas formation within the container to be accommodated without rupture of the container.

A preferred embodiment, especially to aid deformation of the container is that the bottom of the second container is domed.

The container is preferably cylindrical. In one aspect the sides of the cylindrical container taper towards the bottom of the container; preferably the sides taper in a curved manner towards the bottom of the container.

It is highly preferable that the second container further comprises a lid. The lid is used to seal the opening. Preferably the outer surface of the neck of the container has a screw thread which interacts with a corresponding screw thread of the lid.

Composition of the Second Container Oxidizing Composition

The oxidizing composition comprises a material capable of producing pero-oxygen, preferably the material is an inorganic peroxygen material capable of yielding hydrogen peroxide in an aqueous medium and include, but are not limited to: hydrogen peroxide; inorganic alkali metal peroxides (e.g. sodium periodate and sodium peroxide); organic peroxides (e.g. urea peroxide, melamine peroxide); inorganic perhydrate salt bleaching compounds (e.g. alkali metal salts of perborates, percarbonates, perphosphates, persilicates, and persulphates, in some embodiments, sodium salts thereof), which may be incorporated as monohydrates, tetrahydrates, etc.; alkali metal bromates; enzymes; and mixtures thereof. In a preferred embodiments, the per oxygen generating material is hydrogen peroxide.

Preferably the level of per-oxygen generating material is from 1 wt % to 20 wt % of the total composition within the second container, more preferably from 3 wt % to about 15 wt %, most preferably from 6 wt % to 12 wt %.
